However, this optimization method is inefficient and not ideal, particularly for the super high-rise building. This paper introduces a new method of size optimization, using the finite element software Optistruct. Using the new method optimization is completely automatic and also can get every members sensitivity, and then get the ideal result of structure adjustment eventually. The application of the new optimization method is presented in details based on an example of a super high-rise building.
